ANDREW LIPSEY, OF EST HOBOKEN, NEW JERSEY, ASSIGNOR TO WILLIAM BELL, OF NEW YORK, N. Y.

DlSlNTEGRATlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 243,928, dated July 5, 1881.

Application filed October 12,1eso. (No model.)

To all whom it may concern Be it known that I, ANDREW B-. LIPSEY, of 'West Hohoken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Disintegratin g-Machines, of which the following is a specification.

My invention relates to disintegrating mills or machines in which are arranged circular series of heaters, the heaters of alternate series hein g attached to and projecting from a rotary disk, while the heaters of intervening series are attached to and project from a stationary case, or from a disk rotating in an opposite direction to the disk first named. These heaters commonly consist of pins which are separately attached to the disk, each by means of a separate nut; and the object of myinvention is to provide for making and attaching the heaters at a much less cost than is now possible, and especially to enable the several circular series of heaters to be secured much nearer together than when each heater is secured by means of a separate nut.

To this end my invention consists in the combination, with a circular series of heaters for a disintegrating-machine, of an annular or segmental strip integral with the heaters and from which they project. The disk may he provided with annular grooves in its face or faces, and the strip orstrips of metal, after being bent'or producedin a circular form, are inserted into said grooves, and held by means of screws, bolts, or other like means. In order to increase the strength of the fingers or bars which form the heaters, their free ends are connected by a continuous bar, and the whole may be conveniently formed by simply punching holes in a strip of sheet or plate metal of proper width and then bending it into the form of a ring or a segment of aring.

The invention also consists in the combination, in a disintegrating-macl'line, of a disk provided with concentric annular grooves, annular or segmental strips of metal, provided with openings the sides of which form heatingsurfaces, inserted into said grooves, and means for holding them therein.

In combination with a rotary disk provided with heaters of the kind described may be used a second disk rotating in the opposite ditection to the first-mentioned disk, and carrying heaters of the same character, which intervene between the heaters upon the firstmentioned disk; or a single rotary disk and heaters may operate in connection with a stationary case and stationary heaters.

In the accompanying drawings, Figure 1 represents a vertical section through a ma- .chine embodying my invention upon a plane parallel with its shaft. Fig.2 represents a plan of a strip of metal punched so as to form the heaters. Fig. 3 represents a longitudinal section through said strip Fig. 4 represents a plan of a strip of slightly-modified form, and Fig. 5 represents a transverse section of the shaft and deflector of my machine.

Similar letters of reference designate corresponding parts in all the figures.

A designates the'case of the machine, which is of approximately cylindric form, and which is supported upon a bed, B.

O designates a shaft mounted in bearings D upon the bed B, and adapted to be rotated rapidly by means of belts passing over pulleys C,

or by other means.

E designates a disk rigidly fixed upon the rotary shaft 0, and arranged centrally within the case A. I

To the disk E, upon opposite sides thereof, are attached heaters or, arranged in concentric circular series, the heaters upon one side of said disk preferably being intermediate between the series of heaters upon the opposite side thereof.

To the interior of the case A, upon opposite sides, are attached stationary heaters 11, alsoand b might be made of comparatively thick metal and have free outer ends; but in order to greatly strengthen the heaters I preferably connect their free ends by means of continuous bars M, which are also made integral with the heaters.

In the manufacture of the heaters a strip of sheet or plate metal of proper width and thickness is cut orpunched out into the form shown in Fig. 2, the heaters 00 being formed by cutting out holes d at a uniform distance apart, the metal between them constituting the heaters.

In Figs. 1, 2, and 3 the heaters a and b are shown as having smooth straight edges; but in order to increase their efficiencyI may make the edges serrated, or of irregular or zigzag outline, as shown in Fig. 4, so as to act upon the material to be reduced with better results.

In the operation of my machine the material to be disintegrated is introduced through the inlet-openings or hoppers F, and by the centrifugal force generated by the rotation of the disk is thrown outward and successively operated upon by the several series of heaters as itpasses through or between them to the outer circumference of the case, where it is delivered through an outlet or discharge-chute, G.

It will he observed that the openings F, through which the material is introduced into the machine, are over the shaft'O, and to guide or direct the material down each side of said shaft I may attach to the inner sides of the case, just under said openings, inverted-V- shaped deflectors arranged above the shaft, as best seen in Fig. 5. Instead of being V-shaped, the said deflector might be of convex form.

By my invention 1 am enabled to provide disintegrating-machines with heaters of my improved eh aracter at very much less cost than they could be provided with separate heaters each secured in the case separately.

The heaters of each circular series being connected with each other by a continuous strip or bar, a, there is much less liability of their being bent or deflected relatively to adjacent heaters than there is where each heater is made and attached separately, because the bar to forms a brace or stay to each heater, and when the bar a is used to connect their outer or free ends it forms an additional brace or stay to them.

Owing to the circular form of the strips or bars a a the heaters are braced against deflection toward or from the center of the machine. This result is still further attained by inserting the strips or bars a in the grooves in the disk or case, as above described, and the screws or bolts are only necessary for holding said strips or bars in said grooves; hence a very much less number of screws or bolts are necessary than if the heaters were each secured separately.

In case the heaters a should be necessarily of considerable length they may be still further strengthened by connecting them by an intermediate bar or bars between the strips or bars a a It will be clearly understood that in all cases the edges of the heaters a, which are the sides of the openings between them, constitute the beating-surfaces, and, if desirable, I may form beating-surfaces by punching or forming holes or openings of any form in a strip of metal, the sides of the openings constituting the beating-surfaces.

The strips, with the heaters attached, instead of being formed by punching or cutting sheet or plate metal may, perhaps, be more advantageously cast of steel or other metal in circular form.

It is obvious that when the heaters are formed with the continuous bars a a if one edge of the heaters becomes much worn, the strips may be reversed, the bar a? being inserted and secured in the groove instead of the strip a, thus presenting new edges of the heaters for operation and producing the same effect as if the shaft were rotated in the opposite direction. The heaviest work comes upon a certain part or parts of the circumference of the machine, and consequently the stationary heaters at such part or parts are subjected to greater wear than the others. If the screws or bolts which secure the stationary heaters in the grooves be placed equidistant from each other, the heaters of each stationary series may be shifted or turned so as to bring the heaters which are little worn at the part or parts where there is the most wear.

What Iclaim as my invention, and desire to secure by Letters Patent, is-- 1. The combination, with a circular series of heaters for a disintegrating-machine, of an annular or segmental strip integral with the heaters, and from which they project, substantially as and for the purpose specified.

2. The combination, with a disk for a disintegrating-machine provided with concentric annular grooves, of annular or segmental strips of metal inserted into and secured in said grooves and circular series of heaters projecting from and made integral with said strips, substantially as and for the purpose specified.

3. The combination, with a circular series of heaters for a disintegrating-machine, of annular or segmental strips of metal, made inte gral with said heaters, and between which said heaters extend, substantially as and for the purpose specified.

4.. The combination, in a disintegrating-machine, of adisk provided with concentric annular grooves, and annular or segmental strips of metal, inserted into and secured in said grooves, and provided with openings the sides of which form beatingsurfaces, substantially as specified.
